i have approx. 5500 sq. ft. of concrete. its about 1 yr old. a sealer was
put on it after it was poured, but the surface seems to absorb water. i am
considering using a penetrating sealer on it but i am concerned about the
original sealer. do i need to make sure the old sealer is off? if so how
do i remove it? i have a 2500 psi pressurer washer, will that do the
trick? i need your advise. also can you recommend a good sealer? i've
seen some that say you only have to apply it 1 time and never again, is
this true?
I NEED YOUR ADVISE!!! THANKS, JOHN
Concrete Driveway Sealer Video
VIDEO SUMMARY
Concrete driveways are great, but you do not always know if they will installed correctly. In the Tri-state area, a concrete driveway that was installed properly will withstand anything Mother Nature throws at it. But if it was not properly installed or if you are not sure, you better seal it. You can easily apply an application of a silane - siloxane sealer.
First, clean the driveway, brush off all the loose material and be sure it is dry. Be sure to purchase the right sealer. Look on the label for the words silane/siloxane and water repellent. Do not buy silicone sealers. They are bad because they form a film on the surface that does not breathe.
Get a sprayer with the a hand pump. Pour in the sealer and completely spray the driveway. The sealer will dry clear and not change the color of the concrete. It is a simple job. Maybe not as easy as Tim is demonstrating. (Watch the video.)
